the top lower and the presser heads inwardly while theyare in engagement with the rollers, but when the cams have passed the rollers and released them, the springs will force the follower and the presser heads outwardly to free the material and permit its being displacedfrom the mold free of the end presser blocks.

The bottom presser operates between the sides of the mold and serves to lift or displace the pressed material from the mold, and the relation of parts is such that after presser head has coacted with the lower presser headto compress the material, the upper presser head is carried above the top of the mold to a degree which will afford a clearance for the ejection of the finished product from the mold in order that it may be delivered to a take-ofi, as will presently appear. 7

-An upper cross head 38 reciprocates between pairs of guides 39 and 40, and it may a be of a configuration illustrated in Fig. 6

in order that it will have proper guide engaging surfaces such as 41. The cross head 38 has extensions with wrist pins 42 to which bearing blocks 43 are applied. The bearing blocks 25 and 43 are provided with connecting rods or links 44 arranged in pairs on each side of the machine. The rods or links are secured in or to the bearing blocks 25 and reciprocate through the bearing blocks 43, and the upper ends of the rods or links are threaded for the engagement of nuts 45. Springs 46 are applied to the rods or links between the bearing blocks 43 and the nuts, andthe said nuts are adjustable to increase or diminish the pressure of the springs. A

rockshaft 47 is mounted transversely of the cross head 38 and it constitutes a trunnion for the'upper presser head or plunger 17, it being shown that the structure of the presser head or plunger includes an extension or presser bar 48 which projects through a guide 49 secured to the guide posts 39 and 40. Thisrelation of parts insures stability and efiective operation, and results in holding the presser bar 48 of the presser head orplunger centrally of the structure, preventing undue arching or wedging of the brick.

This machine has a conventional type of charger 50 which reciprocates over the bed and the mold and it is operated by links such as 51 that are connected to arms 52 that are oscillatable and moved by means to be presently explained. The presser head 17 is on. the extension or plunger 48 as has been'described, and the manner of connecting these parts may be changed to suit particular requirements, but, in the present embodiment of the invention, they are secured together by fastenings 53, such as screws or the like.

The take-off or device which removes the product from the machine consists of a conveyer apron 54 operating over an idler or roller 55 journaled transversely of the machine in advance of the guides and over a drum or roller 56 suitably journaled in the side members of the frame or in bearings such as 57 applied to the frame. A shaft 58 of the drum 56 has a sprocket wheel or other driven wheel 59 mounted on it and it is engaged by a flexible element (it) such as a sprocket chain that operates over a sprocket wheel 60 rotatable on a rock shaft 61 journaled in the end frames. The sprocket wheel (50 is attached to a gear wheel 62 which is loose on the shaft 61 and the gear Wheel 62 is rotated through its ongagement with a gear wheel A driving shaft 64, which may have power applied to it by any of the well known means for transmitting power, is j ournaled in the frame and it has the sprocket wheel (33 secured to it and it meshes with the gear wheels 21 and 22. A pinion 65 meshes with the gear wheel 62 which, as stated, runs loosely on the rock shaft and through this gearing the conveyor 54 is operated. The arms 52 are mounted on the rock shaft and the rock shaft is rocked through an arm 66 secured on the rock shaft and a link (37 pivoted thereto, which link is oscillatably mounted on a Wrist pin 68 which is extended from the wrist pin 23. As the gear wheel 21 rotates and the Wrist pin 23 is carried around with it, a throw will be imparted to the link (37, which in turn will rock the shaft and op erate the charger.

It will be apparent from an inspection o t the drawing and the description that mate rial will he delivered to the press periodically bv the charger and that after the material or pressed brick has been ejected. and it will by the charger be delivered to the take-off, and through the gearing and instrumentalities described, the finished product may be delivered to any appropriate can rier, from which it may be removed from the machine.

The material is cut in conventional way from a column of plastic material and placed in front of the charger. The means for delivering it to the location in front of the charger does not form a part of the present invention and is therefore not described in detail. its the charger reciprocates over the bed, the material is placed in the mold or press box. \Vhen material is being placed in the press box, the end presser heads have been forced outward, leaving a clearance for the material to descend into the press box. \Vhen material is in said position, the end presser heads are forced toward each other imparting a pressure endwise to the material, while at the same time the lower presser head is moving into the box. causing the' material to be pressed both lilO dill

vertically and horizontally simultaneously. filter the material is pressed, the cams 26 disengage the rollers and allow the presser heads to be forced outwardly by the springs, and these springs are relatively strong in order that this movement of the presser heads outwardly may be practically instan taneous with their release and freeing the brick or finished product to be forced to the top ot the press box by the cam 19. The second or succeeding material being delivered by the charger encounters the finished roduct or brick and pushes it on to the transfer or oil bearing conveyer 54:, which may deliver it to the end where it may be tel-ten oil.

As the description of the operation of the several parts ot the machine has been given in connection with the description ot the parts and their relation to other parts, a further resume of the operation is believed to be unnecessary for an understanding of the invention by one skilled in the art.
